Abstract
Analysis was carried out on seventeen oil samples
namely, palm oils from Kano, Samaru, Funtua and Oyan,
Sunflower oil made by Boulogue Cedex from France, Corn
oil made by Lindenberg from Federal Republic of Germany,
Salad oil, cookwell oil, Melon Seed oil (extracted in
the laboratory) Groundnut oils from Samaru, Funtua and
Kano respectively,
The results show that, Coconut oil and palm kernels
oils have the highest saponification values while the
refined oils or the seed oils have the lower saponification
values. It is evident from the results that all
the refined oils, sunflower, salad, melon, cookwell, corn,
coconut, and groundnut have high iodine numbers while
coconut and palm kernel oils have the least iodine numbers.
It is also evident from the result that acid value
and percentage free fatty acid are very low for oils like,
sunflower, salad, cotton, melon corn, groundnut and palm
oils have high acid and percentage free fatty acids.
Finally, the amount of trace elements found in the
oils are lower in the refined oils than the oils which
are obtained locally
